Bug in code

I updated from cvs at about 2:30 PM and suddenly www.insanejournal.com starting giving a 404 while insanejournal.com was working fine, thankfully I backed up the old source before updating. I wasnt able to detect this on my test server because of the way it is set up (I cant test www.DOMAIN vs. DOMAIN). Does anyone have a test server that can test this out and help debug what is going on? Or at least see if this issue is just local to me?
